GT911 IC Not working in Kitkat iMX6SL

[jansirani]

Hai,

we have a custom board same as iMX6SLEVK design.

we want to integrate 5inch display which is having GT911 Touch IC.

Display is working properly.

we used this link  Re: [PATCH] Input: driver for the Goodix touchpanel — Linux Input and integrated the touch .

I2c is detecting and getevents also coming in the console, but still unable to lock the screen.

Thanks & Regards,

D.Jansirani

Hai igorpadykov

we monitored the i2c scl and sda lines using oscilloscope.

when we touch the screen i2c signals are pulsing but there is no response from the display side.
